”夏ならば感染しないと市民が信じてsocial distancingを放棄すること。行動癖がついて秋になるのが特に危険”だと

夏の気候はウイルスの拡散力を弱めるがパンデミックは止められない https://t.co/lUrG9sWnXf　25Cを超えて以降1C上がるごとにR0が3.1%低下するがそれは劇的なものではない。最も怖いのは夏ならば感染しないと市民が信じてsocial distancingを放棄すること。行動癖がついて秋になるのが特に危険

New research has bolstered the hypothesis that summer’s heat, humidity, abundant sunshine and opportunities for people to get outside should combine to inhibit — though certainly not halt — the spread of the coronavirus.

But infectious-disease experts add a cautionary note: Any benefit from summer conditions would probably be lost if people mistakenly believe the virus can’t spread in warm weather and abandon efforts that limit infections, such as social distancing.


Each additional 1.8-degree temperature increase above that level was associated with an additional 3.1 percent reduction in the virus’s reproduction number, called R0, and pronounced “R naught.

By contrast, higher humidity makes respiratory droplets, the most common vector of virus, drop to the ground or floor more quickly, limiting airborne transmission.

Research published in recent days, looking at how human speech creates small respiratory droplets that can linger in the air for many minutes, has raised anew the question of how the virus spreads and whether some transmission is through these small aerosol droplets. That remains unresolved.

“There’s a certain element of geography-is-destiny here.” The countries with the largest outbreaks and highest mortality rates to date are all in cooler climates, he said.

なるほどねえ。

暑いと多少はいいんだな。

唾だな。おしゃべりしても唾。マスクしてしゃべるとしっとりするもんな、マスクが。

で、空気に湿気があると唾が落下しやすくなって、飛ばなくなるんだ？
